Covalent bonds are formed by the sharing of electrons, which typically occurs between two non-metal atoms that have high electronegativities and a tendency to gain electrons. Metals tend to lose electrons, forming ionic bonds with non-metals. Noble gases are generally inert and do not form bonds.
Explanation:
A galvanic (or voltaic) cell generates electrical energy from a spontaneous chemical reaction. The Daniel cell is a specific, classic type of galvanic cell using zinc and copper electrodes. An electrolytic cell does the reverse, using electrical energy to drive a non-spontaneous chemical reaction.
Explanation:
Oxidation is defined as the loss of electrons (or an increase in oxidation state). A reducing agent is a substance that donates electrons to another species, thereby causing the other species to be reduced. In doing so, the reducing agent itself gets oxidized. Thus, statement 1 is correct, but 2 is incorrect.
